The use cases I'm trying to satisfy are where you need to create content in 
multiple locales, such as a mail-merge where the targets are in different 
locales and the content should be localized.

Thanks for that.

It took me a while to figure out that the country must be in lower case.

KLocale de_DE("kwrite", "de", "DE"); // does not work
KLocale de_DE("kwrite", "de_DE"); // does not work
KLocale de_DE("kwrite", "de_DE.UTF-8"); // does not work
KLocale de_DE("kwrite", "de", "de"); // works!

All the best,

Steve.
